Method and device of map display

Abstract

The embodiment of the invention provides a method and a device of map display. The method of map display comprises the following steps: target data information of map coordinates in the view range of an Flex map is obtained in a locally stored index file by a server, wherein the index file comprises a corresponding relationship between data information and the map coordinates; the target data information is displayed in the view range by the server according to the map coordinates corresponding to the target data information; a coverage capable of rendering each sub-region divided in the view range in advance is overlaid on the Flex map to display by the server through a polymerization algorithm. Key information in complete data information is stored in the data index file, and the data index file is stored in the local server, so that the speed of searching the target data information by the server and the speed of displaying the target data information on the map by the server can be greatly improved, thus the speed and the performance of displaying the data information through an Flex map engine technology can be effectively improved.

Description

technical field [0001] Embodiments of the present invention relate to computer technology and map engine technology, and in particular to a method and device for displaying a map. Background technique [0002] With the development of computer technology and map engine technology, it is necessary to quickly query data information in massive data, and visualize the queried data information on the map. [0003] Animation (Flex) map engine technology can provide animation-style map browsing, and it is a map engine technology that uses Flex technology to display on the basis of Javascript (Js) maps. The Flex map engine technology needs to search the data information on the database of the remote server, and smoothly locate and display the queried data information on the map through the Flex map engine interface. Flex map engine technology can provide users with better visual and operating experience. [0004] Since the huge amount of data information needs to be stored in the d...

Problems solved by technology

[0004] Since the huge amount of data information needs to be stored in the database of the remote server, when it is necessary to use the Flex map engine technology to display the data information on the map, it is necessary to first query the data information and its geographical information on the database of the remote server, so that the Flex Map engine technology is insufficient in the speed of displaying data information
